DRIVING SYSTEM FOR REACTANCE LOAD

摘要

PROBLEM TO BE SOLVED: To incorporate a power supply means controlled to supply an energy of a variable amount to a reactance load with a low power consumption amount. SOLUTION: Reactance elements Lr, Cr are connected to a load Cl through a controllable electronic switch T3 to form a resonance circuit together with the load Cl when the switch T3 is closed. Further, the driving system for a reactance load comprises a means 10 for energizing the switch T3 , an operational amplifier 3 of a power supply means controlled according to a predetermined program for specifying an energy supply to the load Cl, and a controller 14 connected to regulate an operation of the means 10.
